UDP protocol issues - Research Paper Example Reliable and unreliable do not denote whether certain IT tools will perform properly or not, rather it denotes whether the IT tools can deliver guaranteed services. A reliable IT system usually sets up connections and accordingly confirms the accurateness of data transmission and integrity of data. Reliable protocols perform effectively in such a medium which has high tendency to errors. In contrast, an unreliable IT system makes no attempt to develop a connection and do not verify the data. It also does not make any endowment for data recovery or loss of data. Unreliable protocols perform effectively on such kind of medium which has low possibility of data loss and low tendency of error rates. In this context, it can be stated that Transmission Control Protocol (TCP) is considered as a usual reliable protocol and User Datagram Protocol (UDP) is an example of unreliable protocol (Zandy & Miller, 2002). Unreliable Communication and Its Impact on Application Complexity Communication ch annels usually use one of the two types of protocols namely TCP or UDP. In case of TCP i.e. reliable communication, there exists the acknowledgement of received data, while in UDP, no response exists on communication. Thus, in UDP applications, there can be no guarantee for delivery of information or duplication of information. Unreliable communication of UDP minimizes the complexity of applications which help to reduce overhead. UDP applications are usually simpler than TCP applications, as the key objective is to develop a boundary between networking application procedures, operating in higher layers. UDP takes the data, packages it in simplified format, and sends it to the IP address for transmission. This low level of complexity helps to ascertain rapid transmission of information without any delay. Thus, in short, it can be stated that unreliable communication can reduce complexity and increase rapidity of applications (Sinopoli et al., 2004). Issues Related To the Reliability of an Application That Uses UDP There are several applications where UDP is used and one of the most popular applications is Voice over IP (VoIP). Detailed Analysis of the Application VoIP has become one of the newest applications in the internet. Traditionally, voice and signaling data was directed only through dedicated circuit by using standard TCP protocol on physical links such as telephony channel. This exchange of information occurs from both directions at the similar time. In telephony channel, the voice is perceived through microphone and transmitted to the communication channel. However, in VoIP, the voice is electronically encoded through Pulse Code Modulation (PCM) and then directed through internet channel by data packets. Whereas in typical telephony system, voice data are transmitted at a continuous rate, in VoIP, comparatively small data packets are transmitted at a continuous rate. However, the advantage of VoIP over telephony system is that a high-speed network can transport the data packets for different voice channels and also possibly share with other types of data simultaneously (Bu et al., 2006). UDP protocol is used for transmitting voice data on VoIP network. UDP is considered as ‘send and forget’ protocol with no prerequisite for transmitter to recall sent data packets, because it can lead to reaction error (Bu et al., 2006).

Albert Hourani and Ibn Khaldoun Essay Example | Topics and Well Written Essays - 1750 words

Albert Hourani and Ibn Khaldoun - Essay Example Hourani, in his book, presents his political views while he traces the emergence of Islam, which was born into a pagan area influenced by Christianity and Judaism, where the great powers exercised no direct control that is a breeding ground in both the political and religious. A new political order, headed by a new elite, following the Arab tribes of Mecca, went up between the two empires. The precise role that Mohammed has played in these events is uncertain because the history of his time was reconstituted in writing nearly a century after his death. These biographies tell of events concerning his life, his revelation and his action may not have been fabricated. Muhammad began to communicate his message, announcing the end of the world, the arrival of Reckoning, asking to submit to the Will of Allah, the Arabic word for the God of monotheism. His relations with other tribes deteriorated so quickly that he left Mecca for Medina in the Hijra, the Hijra, which marks the beginning of t he Muslim era. In Medina, Muhammad gathered an increased number of supporters and fought to Quraysh. For Ibn Khaldoun, morality matters in the relationship between the individual and the state to the extent that any resolutions or acts taken by the ruler should be evaluated by the moral principles of the society. As one of the great political thinkers and anthropologists, he was greatly affected by the Islamic traditions that values morality above one’s own interests.
